From 9dbf8dc7a96a8020e0ee05926ef7a3f976e9c318 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Wed, 11 Nov 2020 15:54:00 -0800 Subject: [PATCH] pointer-compare-1.c: Add __attribute__((used)) c-c++-common/asan/pointer-compare-1.c assumes the certain order for variable placement. Add __attribute__((used)) to avoid variable placement changes due to SHF_GNU_RETAIN.
